If there's one complaint I have, it's how difficult it is to recover HP and mana. Resting at an inn only gives you 35 mana and no HP. So, you're forced to buy HP and mana recovery items to recover. But making money is tough in the game, too. I see it as a real possibility to just get stuck in the game where you can't afford to buy items or pay for a room, and you can't advance the story because you're too weak to win a fight. It's too complicated for such a simple game. Just do what every other game does, recover all your HP and mana when you rest. We're not playing XCOM over here. You should just keep it simple.
